The reliability issue of low-voltage power line communication is the biggest problem impeding its universal application. The domestic and foreign scholars＇ research results of frequency selection, input impedance, noise interference and signal attenuation characteristics are described. The noise interference characteristic has the greatest impact on the reliability of low-voltage power line communication. This paper introduces the classification, features and modeling research of the noise interference. By analyzing the existing mathematical models of the characteristics, we conclude that the establishment of accurate models is the foundation of improving the reliability of low-voltage power line communication. and will be the important direction of power line communication development in the future.
